Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Group 1 - High-intensity functional training (HIFT)
The HIFT intervention will be supervised by a certified fitness professional. HIFT will include both “cardio” or “resistance” sessions. The cardio sessions include body weight and dynamic movements which target the aerobic and anaerobic energy systems. The resistance sessions use weighted functional movement patterns to target muscle mass, strength, and power. Both the cardio and resistance sessions last a total of 45 minutes. Participants will initially be prescribed one exercise session per week (aerobic session) in week 1, two exercise sessions per week (1 aerobic sessions and 1 resistance session) in week 2. From week 3, participants will be asked to attend three HIFT (2 aerobic sessions and 1 resistance session) classes per week.

Location where intervention will be delivered: F45® Bulli or Corrimal,
Mode of delivery: the exercise sessions will be delivered in groups of no more than 30 people per class.
Duration of intervention: 12 weeks.
Intensity of duration: participants will be asked to work out at an intensity equivalent to 13-17 RPE during the active exercise period.
Examples of exercises prescribed as part of the intervention: squats (bodyweight and weighted back squats), deadlift, push-press, medicine ball throws, skipping (including double-unders) and more.
Adherence: Adherence will be monitored through session attendance checklists and HR will be recorded by a HR monitor.

Group 2 - Physical Activity Guidelines (PAG)
Participants in PAG will be prescribed an exercise program that is consistent with current Australian physical activity guidelines for 12 weeks. This includes instruction to undertake 150 min of moderate-intensity or 75 min of vigorous-intensity aerobic exercise per week in addition to two resistance training sessions per week. Participants will be asked to attend the Illawarra Health and Medical Research Institute to undertake supervised resistance training sessions two times per week which will include 4 upper body exercises, 2 lower body exercises, and 1 core exercise. Participants will have their exercise behaviour monitored weekly via text messages.
Duration of intervention: 12 weeks.
Duration of resistance training sessions: 1-hr.
Supervision of exercise: resistance training will be supervised by an Accredited Exercise Scientist, Accredited Exercise Physiologist, or by an Accredited Exercise Physiologist clinical placement student under the guidance of an Accredited Exercise Physiologist.
Mode of delivery: one-on-one or in groups of no more than 6 people.
Resistance training prescription: 3 Sets of 10-12 repetitions at 55-75% 1RM.
Text messages: Weekly text messages will be sent to remind participants to undertake 150 minutes of moderate aerobic exercise per week. the text messages will also include their resistance training session details including time and locations.
Adherence: resistance training sessions will be monitored by session attendance sheets and aerobic exercise will be monitored through a Fitbit wrist monitor.

Once the 12-week intervention period has elapsed and the follow-up assessments have been completed, participants will be offered HIFT but no further data will be collected.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Randomisation will be conducted by a research officer at NICM Health Research Institute external to the primary research team (investigators listed at the start of this document). This person will allocate 60 consecutively numbered identifiers to sealed opaque envelopes that will contain the ID number and allocation ( 20 HIFT, 20 PAG, and 20 control).
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The research officer (external to research group) will produce computer generated randomisation treatment sequences, which randomly associate a randomisation number with either the HIFT, PAG, or control group. Randomisation numbers will be allocated in permuted blocks of 6 randomisation numbers starting from 01 to 60 with each block containing 2 HIFT, 2 PAG and 2 CTRL assigned randomisation numbers.

Efficacy
Statistical methods / analysis
The primary analysis will determine the effects between the interventions and CTRL groups for change in physical performance and cardiometabolic outcomes, which will be assessed by ANCOVA using the baseline value as the covariate. Within-group changes will be determined via paired-sample t tests or the non-parametric alternative (Wilcoxon signed-rank test) for non-normally distributed data.

Secondary analyses will determine the relationships among changes in key cardiometabolic outcomes with associated demographic, psychometric, biochemical and inflammatory, and exercise performance parameters through correlation coefficients. Separate linear regressions will be undertaken to determine the relative contribution of changes in specific variables on key cardiometabolic outcomes.

Summary
Brief summary
Women with polycystic ovary syndrome (PCOS) are at an increased risk of developing cardiometabolic complications which can include insulin resistance, damaged blood vessels, type 2 diabetes, and heart disease. Some studies have shown that regular exercise can help to reduce tissue fat levels, improve glucose control, blood flow and fitness. However, the optimal type and dose of exercise for health improvement in women with polycystic ovary syndrome is unclear.

Recently, high-intensity functional training (HIFT) has become increasingly popular, particularly among younger women. This form of training focuses on performing repeated functional, multi-joint movements which can incorporate aerobic and/or muscle-strengthening components. Consequently, we aim to determine whether this form of training can improve fitness and health outcomes in women with PCOS. We’ll be comparing the effectiveness of HIFT on physical fitness and cardiometabolic outcomes to an exercise program matching the current physical activity guidelines, as well as to usual-care in women with PCOS. The results produced from this study will provide a greater evidence base for future physical activity guidelines for PCOS.
